Technologies for dividing work across accelerator devices

ABSTRACT

Technologies for dividing work across one or more accelerator devices include a compute device. The compute device is to determine a configuration of each of multiple accelerator devices of the compute device, receive a job to be accelerated from a requester device remote from the compute device, and divide the job into multiple tasks for a parallelization of the multiple tasks among the one or more accelerator devices, as a function of a job analysis of the job and the configuration of each accelerator device. The compute engine is further to schedule the tasks to the one or more accelerator devices based on the job analysis and execute the tasks on the one or more accelerator devices for the parallelization of the multiple tasks to obtain an output of the job.

BACKGROUND

Demand for accelerator devices has continued to increase because the accelerator devices are becoming more important as they may be used in various technological areas, such as machine learning and genomics. Typical architectures for accelerator devices, such as field programmable gate arrays (FPGAs), cryptography accelerators, graphics accelerators, and/or compression accelerators (referred to herein as “accelerator devices,” “accelerators,” or “accelerator resources”) capable of accelerating the execution of a set of operations in a workload (e.g., processes, applications, services, etc.) may allow static assignment of specified amounts of shared resources of the accelerator device (e.g., high bandwidth memory, data storage, etc.) among different portions of the logic (e.g., circuitry) of the accelerator device. Typically, the workload is allocated with the required processor(s), memory, and accelerator device(s) for the duration of the workload. The workload may use its allocated accelerator device at any point of time; however, in many cases, the accelerator devices will remain idle leading to wastage of resources.

FIG. 1 illustrates a conceptual overview of a data center 100 that may generally be representative of a data center or other type of computing network in/for which one or more techniques described herein may be implemented according to various embodiments. As shown in FIG. 1, data center 100 may generally contain a plurality of racks, each of which may house computing equipment comprising a respective set of physical resources. In the particular non-limiting example depicted in FIG. 1, data center 100 contains four racks 102A to 102D, which house computing equipment comprising respective sets of physical resources (PCRs) 105A to 105D. According to this example, a collective set of physical resources 106 of data center 100 includes the various sets of physical resources 105A to 105D that are distributed among racks 102A to 102D. Physical resources 106 may include resources of multiple types, such as—for example—processors, co-processors, accelerators, field programmable gate arrays (FPGAs), memory, and storage. The embodiments are not limited to these examples.

The illustrative data center 100 differs from typical data centers in many ways. For example, in the illustrative embodiment, the circuit boards (“sleds”) on which components such as CPUs, memory, and other components are placed are designed for increased thermal performance. In particular, in the illustrative embodiment, the sleds are shallower than typical boards. In other words, the sleds are shorter from the front to the back, where cooling fans are located. This decreases the length of the path that air must to travel across the components on the board. Further, the components on the sled are spaced further apart than in typical circuit boards, and the components are arranged to reduce or eliminate shadowing (i.e., one component in the air flow path of another component). In the illustrative embodiment, processing components such as the processors are located on a top side of a sled while near memory, such as DIMMs, are located on a bottom side of the sled. As a result of the enhanced airflow provided by this design, the components may operate at higher frequencies and power levels than in typical systems, thereby increasing performance. Furthermore, the sleds are configured to blindly mate with power and data communication cables in each rack 102A, 102B, 102C, 102D, enhancing their ability to be quickly removed, upgraded, reinstalled, and/or replaced. Similarly, individual components located on the sleds, such as processors, accelerators, memory, and data storage drives, are configured to be easily upgraded due to their increased spacing from each other. In the illustrative embodiment, the components additionally include hardware attestation features to prove their authenticity.

Furthermore, in the illustrative embodiment, the data center 100 utilizes a single network architecture (“fabric”) that supports multiple other network architectures including Ethernet and Omni-Path. The sleds, in the illustrative embodiment, are coupled to switches via optical fibers, which provide higher bandwidth and lower latency than typical twisted pair cabling (e.g., Category 5, Category 5e, Category 6, etc.). Due to the high bandwidth, low latency interconnections and network architecture, the data center 100 may, in use, pool resources, such as memory, accelerators (e.g., graphics accelerators, FPGAs, ASICs, etc.), and data storage drives that are physically disaggregated, and provide them to compute resources (e.g., processors) on an as needed basis, enabling the compute resources to access the pooled resources as if they were local. The illustrative data center 100 additionally receives utilization information for the various resources, predicts resource utilization for different types of workloads based on past resource utilization, and dynamically reallocates the resources based on this information.

The racks 102A, 102B, 102C, 102D of the data center 100 may include physical design features that facilitate the automation of a variety of types of maintenance tasks. For example, data center 100 may be implemented using racks that are designed to be robotically-accessed, and to accept and house robotically-manipulatable resource sleds. Furthermore, in the illustrative embodiment, the racks 102A, 102B, 102C, 102D include integrated power sources that receive a greater voltage than is typical for power sources. The increased voltage enables the power sources to provide additional power to the components on each sled, enabling the components to operate at higher than typical frequencies.

FIG. 2 illustrates an exemplary logical configuration of a rack 202 of the data center 100. As shown in FIG. 2, rack 202 may generally house a plurality of sleds, each of which may comprise a respective set of physical resources. In the particular non-limiting example depicted in FIG. 2, rack 202 houses sleds 204-1 to 204-4 comprising respective sets of physical resources 205-1 to 205-4, each of which constitutes a portion of the collective set of physical resources 206 comprised in rack 202. With respect to FIG. 1, if rack 202 is representative of—for example—rack 102A, then physical resources 206 may correspond to the physical resources 105A comprised in rack 102A. In the context of this example, physical resources 105A may thus be made up of the respective sets of physical resources, including physical storage resources 205-1, physical accelerator resources 205-2, physical memory resources 205-3, and physical compute resources 205-5 comprised in the sleds 204-1 to 204-4 of rack 202. The embodiments are not limited to this example. Each sled may contain a pool of each of the various types of physical resources (e.g., compute, memory, accelerator, storage). By having robotically accessible and robotically manipulatable sleds comprising disaggregated resources, each type of resource can be upgraded independently of each other and at their own optimized refresh rate.

FIG. 3 illustrates an example of a data center 300 that may generally be representative of one in/for which one or more techniques described herein may be implemented according to various embodiments. In the particular non-limiting example depicted in FIG. 3, data center 300 comprises racks 302-1 to 302-32. In various embodiments, the racks of data center 300 may be arranged in such fashion as to define and/or accommodate various access pathways. For example, as shown in FIG. 3, the racks of data center 300 may be arranged in such fashion as to define and/or accommodate access pathways 311A, 311B, 311C, and 311D. In some embodiments, the presence of such access pathways may generally enable automated maintenance equipment, such as robotic maintenance equipment, to physically access the computing equipment housed in the various racks of data center 300 and perform automated maintenance tasks (e.g., replace a failed sled, upgrade a sled). In various embodiments, the dimensions of access pathways 311A, 311B, 311C, and 311D, the dimensions of racks 302-1 to 302-32, and/or one or more other aspects of the physical layout of data center 300 may be selected to facilitate such automated operations. The embodiments are not limited in this context.

FIG. 4 illustrates an example of a data center 400 that may generally be representative of one in/for which one or more techniques described herein may be implemented according to various embodiments. As shown in FIG. 4, data center 400 may feature an optical fabric 412. Optical fabric 412 may generally comprise a combination of optical signaling media (such as optical cabling) and optical switching infrastructure via which any particular sled in data center 400 can send signals to (and receive signals from) each of the other sleds in data center 400. The signaling connectivity that optical fabric 412 provides to any given sled may include connectivity both to other sleds in a same rack and sleds in other racks. In the particular non-limiting example depicted in FIG. 4, data center 400 includes four racks 402A to 402D. Racks 402A to 402D house respective pairs of sleds 404A-1 and 404A-2, 404B-1 and 404B-2, 404C-1 and 404C-2, and 404D-1 and 404D-2. Thus, in this example, data center 400 comprises a total of eight sleds. Via optical fabric 412, each such sled may possess signaling connectivity with each of the seven other sleds in data center 400. For example, via optical fabric 412, sled 404A-1 in rack 402A may possess signaling connectivity with sled 404A-2 in rack 402A, as well as the six other sleds 404B-1, 404B-2, 404C-1, 404C-2, 404D-1, and 404D-2 that are distributed among the other racks 402B, 402C, and 402D of data center 400. The embodiments are not limited to this example.

FIG. 5 illustrates an overview of a connectivity scheme 500 that may generally be representative of link-layer connectivity that may be established in some embodiments among the various sleds of a data center, such as any of example data centers 100, 300, and 400 of FIGS. 1, 3, and 4. Connectivity scheme 500 may be implemented using an optical fabric that features a dual-mode optical switching infrastructure 514. Dual-mode optical switching infrastructure 514 may generally comprise a switching infrastructure that is capable of receiving communications according to multiple link-layer protocols via a same unified set of optical signaling media, and properly switching such communications. In various embodiments, dual-mode optical switching infrastructure 514 may be implemented using one or more dual-mode optical switches 515. In various embodiments, dual-mode optical switches 515 may generally comprise high-radix switches. In some embodiments, dual-mode optical switches 515 may comprise multi-ply switches, such as four-ply switches. In various embodiments, dual-mode optical switches 515 may feature integrated silicon photonics that enable them to switch communications with significantly reduced latency in comparison to conventional switching devices. In some embodiments, dual-mode optical switches 515 may constitute leaf switches 530 in a leaf-spine architecture additionally including one or more dual-mode optical spine switches 520.

In various embodiments, dual-mode optical switches may be capable of receiving both Ethernet protocol communications carrying Internet Protocol (IP packets) and communications according to a second, high-performance computing (HPC) link-layer protocol (e.g., Intel's Omni-Path Architecture's, Infiniband) via optical signaling media of an optical fabric. As reflected in FIG. 5, with respect to any particular pair of sleds 504A and 504B possessing optical signaling connectivity to the optical fabric, connectivity scheme 500 may thus provide support for link-layer connectivity via both Ethernet links and HPC links. Thus, both Ethernet and HPC communications can be supported by a single high-bandwidth, low-latency switch fabric. The embodiments are not limited to this example.

FIG. 6 illustrates a general overview of a rack architecture 600 that may be representative of an architecture of any particular one of the racks depicted in FIGS. 1 to 4 according to some embodiments. As reflected in FIG. 6, rack architecture 600 may generally feature a plurality of sled spaces into which sleds may be inserted, each of which may be robotically-accessible via a rack access region 601. In the particular non-limiting example depicted in FIG. 6, rack architecture 600 features five sled spaces 603-1 to 603-5. Sled spaces 603-1 to 603-5 feature respective multi-purpose connector modules (MPCMs) 616-1 to 616-5.

FIG. 7 illustrates an example of a sled 704 that may be representative of a sled of such a type. As shown in FIG. 7, sled 704 may comprise a set of physical resources 705, as well as an MPCM 716 designed to couple with a counterpart MPCM when sled 704 is inserted into a sled space such as any of sled spaces 603-1 to 603-5 of FIG. 6. Sled 704 may also feature an expansion connector 717. Expansion connector 717 may generally comprise a socket, slot, or other type of connection element that is capable of accepting one or more types of expansion modules, such as an expansion sled 718. By coupling with a counterpart connector on expansion sled 718, expansion connector 717 may provide physical resources 705 with access to supplemental computing resources 705B residing on expansion sled 718. The embodiments are not limited in this context.

FIG. 8 illustrates an example of a rack architecture 800 that may be representative of a rack architecture that may be implemented in order to provide support for sleds featuring expansion capabilities, such as sled 704 of FIG. 7. In the particular non-limiting example depicted in FIG. 8, rack architecture 800 includes seven sled spaces 803-1 to 803-7, which feature respective MPCMs 816-1 to 816-7. Sled spaces 803-1 to 803-7 include respective primary regions 803-1A to 803-7A and respective expansion regions 803-1B to 803-7B. With respect to each such sled space, when the corresponding MPCM is coupled with a counterpart MPCM of an inserted sled, the primary region may generally constitute a region of the sled space that physically accommodates the inserted sled. The expansion region may generally constitute a region of the sled space that can physically accommodate an expansion module, such as expansion sled 718 of FIG. 7, in the event that the inserted sled is configured with such a module.

FIG. 9 illustrates an example of a rack 902 that may be representative of a rack implemented according to rack architecture 800 of FIG. 8 according to some embodiments. In the particular non-limiting example depicted in FIG. 9, rack 902 features seven sled spaces 903-1 to 903-7, which include respective primary regions 903-1A to 903-7A and respective expansion regions 903-1B to 903-7B. In various embodiments, temperature control in rack 902 may be implemented using an air cooling system. For example, as reflected in FIG. 9, rack 902 may feature a plurality of fans 919 that are generally arranged to provide air cooling within the various sled spaces 903-1 to 903-7. In some embodiments, the height of the sled space is greater than the conventional “1 U” server height. In such embodiments, fans 919 may generally comprise relatively slow, large diameter cooling fans as compared to fans used in conventional rack configurations. Running larger diameter cooling fans at lower speeds may increase fan lifetime relative to smaller diameter cooling fans running at higher speeds while still providing the same amount of cooling. The sleds are physically shallower than conventional rack dimensions. Further, components are arranged on each sled to reduce thermal shadowing (i.e., not arranged serially in the direction of air flow). As a result, the wider, shallower sleds allow for an increase in device performance because the devices can be operated at a higher thermal envelope (e.g., 250 W) due to improved cooling (i.e., no thermal shadowing, more space between devices, more room for larger heat sinks, etc.).

MPCMs 916-1 to 916-7 may be configured to provide inserted sleds with access to power sourced by respective power modules 920-1 to 920-7, each of which may draw power from an external power source 921. In various embodiments, external power source 921 may deliver alternating current (AC) power to rack 902, and power modules 920-1 to 920-7 may be configured to convert such AC power to direct current (DC) power to be sourced to inserted sleds. In some embodiments, for example, power modules 920-1 to 920-7 may be configured to convert 277-volt AC power into 12-volt DC power for provision to inserted sleds via respective MPCMs 916-1 to 916-7. The embodiments are not limited to this example.

MPCMs 916-1 to 916-7 may also be arranged to provide inserted sleds with optical signaling connectivity to a dual-mode optical switching infrastructure 914, which may be the same as—or similar to—dual-mode optical switching infrastructure 514 of FIG. 5. In various embodiments, optical connectors contained in MPCMs 916-1 to 916-7 may be designed to couple with counterpart optical connectors contained in MPCMs of inserted sleds to provide such sleds with optical signaling connectivity to dual-mode optical switching infrastructure 914 via respective lengths of optical cabling 922-1 to 922-7. In some embodiments, each such length of optical cabling may extend from its corresponding MPCM to an optical interconnect loom 923 that is external to the sled spaces of rack 902. In various embodiments, optical interconnect loom 923 may be arranged to pass through a support post or other type of load-bearing element of rack 902. The embodiments are not limited in this context. Because inserted sleds connect to an optical switching infrastructure via MPCMs, the resources typically spent in manually configuring the rack cabling to accommodate a newly inserted sled can be saved.

FIG. 10 illustrates an example of a sled 1004 that may be representative of a sled designed for use in conjunction with rack 902 of FIG. 9 according to some embodiments. Sled 1004 may feature an MPCM 1016 that comprises an optical connector 1016A and a power connector 1016B, and that is designed to couple with a counterpart MPCM of a sled space in conjunction with insertion of MPCM 1016 into that sled space. Coupling MPCM 1016 with such a counterpart MPCM may cause power connector 1016 to couple with a power connector comprised in the counterpart MPCM. This may generally enable physical resources 1005 of sled 1004 to source power from an external source, via power connector 1016 and power transmission media 1024 that conductively couples power connector 1016 to physical resources 1005.

Sled 1004 may also include dual-mode optical network interface circuitry 1026. Dual-mode optical network interface circuitry 1026 may generally comprise circuitry that is capable of communicating over optical signaling media according to each of multiple link-layer protocols supported by dual-mode optical switching infrastructure 914 of FIG. 9. In some embodiments, dual-mode optical network interface circuitry 1026 may be capable both of Ethernet protocol communications and of communications according to a second, high-performance protocol. In various embodiments, dual-mode optical network interface circuitry 1026 may include one or more optical transceiver modules 1027, each of which may be capable of transmitting and receiving optical signals over each of one or more optical channels. The embodiments are not limited in this context.

Coupling MPCM 1016 with a counterpart MPCM of a sled space in a given rack may cause optical connector 1016A to couple with an optical connector comprised in the counterpart MPCM. This may generally establish optical connectivity between optical cabling of the sled and dual-mode optical network interface circuitry 1026, via each of a set of optical channels 1025. Dual-mode optical network interface circuitry 1026 may communicate with the physical resources 1005 of sled 1004 via electrical signaling media 1028. In addition to the dimensions of the sleds and arrangement of components on the sleds to provide improved cooling and enable operation at a relatively higher thermal envelope (e.g., 250 W), as described above with reference to FIG. 9, in some embodiments, a sled may include one or more additional features to facilitate air cooling, such as a heatpipe and/or heat sinks arranged to dissipate heat generated by physical resources 1005. It is worthy of note that although the example sled 1004 depicted in FIG. 10 does not feature an expansion connector, any given sled that features the design elements of sled 1004 may also feature an expansion connector according to some embodiments. The embodiments are not limited in this context.

FIG. 11 illustrates an example of a data center 1100 that may generally be representative of one in/for which one or more techniques described herein may be implemented according to various embodiments. As reflected in FIG. 11, a physical infrastructure management framework 1150A may be implemented to facilitate management of a physical infrastructure 1100A of data center 1100. In various embodiments, one function of physical infrastructure management framework 1150A may be to manage automated maintenance functions within data center 1100, such as the use of robotic maintenance equipment to service computing equipment within physical infrastructure 1100A. In some embodiments, physical infrastructure 1100A may feature an advanced telemetry system that performs telemetry reporting that is sufficiently robust to support remote automated management of physical infrastructure 1100A. In various embodiments, telemetry information provided by such an advanced telemetry system may support features such as failure prediction/prevention capabilities and capacity planning capabilities. In some embodiments, physical infrastructure management framework 1150A may also be configured to manage authentication of physical infrastructure components using hardware attestation techniques. For example, robots may verify the authenticity of components before installation by analyzing information collected from a radio frequency identification (RFID) tag associated with each component to be installed. The embodiments are not limited in this context.

As shown in FIG. 11, the physical infrastructure 1100A of data center 1100 may comprise an optical fabric 1112, which may include a dual-mode optical switching infrastructure 1114. Optical fabric 1112 and dual-mode optical switching infrastructure 1114 may be the same as—or similar to—optical fabric 412 of FIG. 4 and dual-mode optical switching infrastructure 514 of FIG. 5, respectively, and may provide high-bandwidth, low-latency, multi-protocol connectivity among sleds of data center 1100. As discussed above, with reference to FIG. 1, in various embodiments, the availability of such connectivity may make it feasible to disaggregate and dynamically pool resources such as accelerators, memory, and storage. In some embodiments, for example, one or more pooled accelerator sleds 1130 may be included among the physical infrastructure 1100A of data center 1100, each of which may comprise a pool of accelerator resources—such as co-processors and/or FPGAs, for example—that is globally accessible to other sleds via optical fabric 1112 and dual-mode optical switching infrastructure 1114.

In another example, in various embodiments, one or more pooled storage sleds 1132 may be included among the physical infrastructure 1100A of data center 1100, each of which may comprise a pool of storage resources that is globally accessible to other sleds via optical fabric 1112 and dual-mode optical switching infrastructure 1114. In some embodiments, such pooled storage sleds 1132 may comprise pools of solid-state storage devices such as solid-state drives (SSDs). In various embodiments, one or more high-performance processing sleds 1134 may be included among the physical infrastructure 1100A of data center 1100. In some embodiments, high-performance processing sleds 1134 may comprise pools of high-performance processors, as well as cooling features that enhance air cooling to yield a higher thermal envelope of up to 250 W or more. In various embodiments, any given high-performance processing sled 1134 may feature an expansion connector 1117 that can accept a far memory expansion sled, such that the far memory that is locally available to that high-performance processing sled 1134 is disaggregated from the processors and near memory comprised on that sled. In some embodiments, such a high-performance processing sled 1134 may be configured with far memory using an expansion sled that comprises low-latency SSD storage. The optical infrastructure allows for compute resources on one sled to utilize remote accelerator/FPGA, memory, and/or SSD resources that are disaggregated on a sled located on the same rack or any other rack in the data center. The remote resources can be located one switch jump away or two-switch jumps away in the spine-leaf network architecture described above with reference to FIG. 5. The embodiments are not limited in this context.

In various embodiments, one or more layers of abstraction may be applied to the physical resources of physical infrastructure 1100A in order to define a virtual infrastructure, such as a software-defined infrastructure 1100B. In some embodiments, virtual computing resources 1136 of software-defined infrastructure 1100B may be allocated to support the provision of cloud services 1140. In various embodiments, particular sets of virtual computing resources 1136 may be grouped for provision to cloud services 1140 in the form of SDI services 1138. Examples of cloud services 1140 may include—without limitation—software as a service (SaaS) services 1142, platform as a service (PaaS) services 1144, and infrastructure as a service (IaaS) services 1146.

In some embodiments, management of software-defined infrastructure 1100B may be conducted using a virtual infrastructure management framework 1150B. In various embodiments, virtual infrastructure management framework 1150B may be designed to implement workload fingerprinting techniques and/or machine-learning techniques in conjunction with managing allocation of virtual computing resources 1136 and/or SDI services 1138 to cloud services 1140. In some embodiments, virtual infrastructure management framework 1150B may use/consult telemetry data in conjunction with performing such resource allocation. In various embodiments, an application/service management framework 1150C may be implemented in order to provide QoS management capabilities for cloud services 1140. The embodiments are not limited in this context.

Referring now to FIG. 12, a system 1200, which may be implemented in accordance with the data centers 100, 300, 400, 1100 described above with reference to FIGS. 1, 3, 4, and 11, for dividing work across one or more accelerator devices includes an orchestrator server 1204 in communication with accelerator sleds 1202 (e.g., physical accelerator resources 205-2 or pooled accelerator sleds 1130), a compute sled 1206 (e.g., physical compute resources 205-4), and a memory sled 1208 (e.g., physical memory resources 205-3) from the same or different racks (e.g., one or more of racks 302-1 through 302-32). In use, a micro-orchestrator logic unit 1220 of each accelerator sled 1204 is configured to receive a job requested to be accelerated from the compute sled 1206 executing (e.g., with a central processing unit (CPU) 1262) an application 1262 (e.g., a workload). The micro-orchestrator logic unit 1220 is configured to analyze the requested job in order to determine how to divide the job into multiple tasks (e.g., operations, processes, functions, etc.) that may be executed in parallel on one or more accelerator devices 1222 to maximize the parallelization of the tasks to minimize an amount of time required to complete the requested job. It should be appreciated that each accelerator device 1222 may concurrently execute more than one task. In some embodiments, the orchestrator server 1204 may choose to determine how to divide the tasks across one or more accelerator devices 1222 on the same or different accelerator sleds 1202, such as based on a job analysis received from the micro-orchestrator logic unit 1220 of each accelerator sleds 1202.

While two accelerator sleds 1202, one compute sled 1206, and one memory sled 1208 are shown in FIG. 12, it should be understood that in other embodiments, the system 1200 may include a different number of accelerator sleds 1202, the compute sleds 1206, memory sleds 1208, and/or other sleds (e.g., storage sleds). The system 1200 may be located in a data center and provide storage and compute services (e.g., cloud services) to a client device 1210 that is in communication with the system 1200 through a network 1212. The orchestrator server 1204 may support a cloud operating environment, such as OpenStack, and the accelerator sleds 1202, the compute sled 1206, and the storage sled 1208 may execute one or more applications or processes (i.e., workloads), such as in virtual machines or containers.

As shown in FIG. 12, the client device 1210, the orchestrator server 1204, and the sleds of the system 1200 (e.g., the accelerator sleds 1202, the compute sled 1206, and the memory sled 1208) are illustratively in communication via the network 1212, which may be embodied as any type of wired or wireless communication network, including global networks (e.g., the Internet), local area networks (LANs) or wide area networks (WANs), cellular networks (e.g., Global System for Mobile Communications (GSM), 3G, Long Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMAX), etc.), digital subscriber line (DSL) networks, cable networks (e.g., coaxial networks, fiber networks, etc.), or any combination thereof.

In the illustrative embodiment, each accelerator sled 1202 includes the micro-orchestrator logic unit 1220 and two accelerator devices 1222, and each accelerator device 1222 includes two kernels (e.g., each a set of circuitry and/or executable code usable to implement a set of functions) 1224. It should be appreciated that, in other embodiments, each orchestrator sled 1202 may include a different number of accelerator devices 1222, and each accelerator device 1222 may include a different number of kernels 1224. It should be appreciated that some accelerator sleds 1202 (e.g., the accelerator sled 1202 a) may include an inter-accelerator communication interface 1226 (e.g., a high speed serial interface (HSSI)) between the accelerator devices 1222. The inter-accelerator communication interface 1226 is configured to communicatively connect the accelerator devices 1222 of the accelerator sled 1202 a to share data. For example, accelerator devices 1222 concurrently executing tasks that share a data set may access to the same data set at the same time in order to read from and/or write to different parts of the data set. To do so, the accelerator devices 1222 of the accelerator sled 1202 a share the data set via the inter-accelerator communication interface 1226. Alternatively, in some embodiments, the accelerator devices 1222 may share data that is present in shared memory (e.g., a shared virtual memory 1282). It should be appreciated that, in such embodiments, the accelerator devices 1222 need not be on the same accelerator sled 1202 to concurrently execute tasks that share the data.

The memory sled 1208, in the illustrative embodiment, includes a memory device 1280, which further includes the shared virtual memory 1282. As described above, the shared virtual memory 1282 may hold data that can be accessed by any of the accelerator devices 1222 capable of utilizing shared virtual memory. For example, the accelerator devices 1222 on an accelerator sled 1202 (e.g., the accelerator sled 1202 b) that does not have an inter-accelerator communication interface 1226 (e.g., a HSSI) may use the shared data stored in the shared virtual memory 1282 to execute tasks in parallel. Additionally, the accelerator devices 1222 on different accelerator sleds 1202 (e.g., accelerator sleds 1202 a, 1202 b) may use the shared data stored in the shared virtual memory 1282 to execute the tasks in parallel. It should be appreciated that, in some embodiments, the accelerator devices 1222 that are communicatively connected to each other via the HSSI 1226 may share data via the shared virtual memory 1282 and/or the inter-accelerator communication interface 1226, as dictated by a micro-orchestrator logic unit 1220 and/or the orchestrator server 1204.

Referring now to FIG. 13, each accelerator sled 1202 may be embodied as any type of compute device capable of performing the functions described herein. For example, the accelerator sled 1202 may be embodied as a sled 204-2 with physical accelerator resources 205-2, a computer, a server, a multiprocessor system, a network appliance (e.g., physical or virtual), a desktop computer, a workstation, a laptop computer, a notebook computer, a processor-based system, or a network appliance. As shown in FIG. 13, the illustrative accelerator sled 1202 includes a compute engine 1310, an input/output (“I/O”) subsystem 1320, communication circuitry 1330, and an accelerator subsystem 1340. It should be appreciated that the accelerator sled 1202 may include other or additional components, such as those commonly found in a typical computing device (e.g., various input/output devices and/or other components), in other embodiments. Additionally, in some embodiments, one or more of the illustrative components may be incorporated in, or otherwise form a portion of, another component.

The compute engine 1310 may be embodied as any type of device or collection of devices capable of performing the various compute functions as described below. In some embodiments, the compute engine 1310 may be embodied as a single device such as an integrated circuit, an embedded system, a field-programmable-array (FPGA), a system-on-a-chip (SOC), an application specific integrated circuit (ASIC), reconfigurable hardware or hardware circuitry, or other specialized hardware to facilitate performance of the functions described herein. Additionally, in some embodiments, the compute engine 1310 may include, or may be embodied as, a CPU 1312 and memory 1314. The CPU 1312 may be embodied as any type of processor capable of performing the functions described herein. For example, the CPU 1312 may be embodied as a single or multi-core processor(s), digital signal processor, microcontroller, or other processor or processing/controlling circuit.

In some embodiments, the CPU 1312 may include a micro-orchestrator logic unit 1220 which may be embodied as any device or circuitry capable of determining the capabilities (e.g., functions that each accelerator device 1222 is capable of accelerating, the present load on each accelerator device 1222, whether each accelerator device 1222 is capable of accessing shared memory or communicating through an inter-accelerator communication interface, etc.) of the accelerator devices 1222 on the accelerator sled 1202, and dynamically dividing a job into tasks to be performed by one or more of the accelerator devices 1222 as a function of the determined capabilities of the accelerator devices 1222 and identified tasks within the job that would benefit from different types of acceleration (e.g., cryptographic acceleration, compression acceleration, parallel execution, etc.). For example, the micro-orchestrator logic unit 1220 may be embodied as a co-processor, embedded circuit, ASIC, FPGA, and/or other specialized circuitry. The micro-orchestrator logic unit 1220 may receive a request directly from a compute sled 1206 executing an application with a job to be accelerated. Alternatively, the micro-orchestrator logic unit 1220 may receive a request from the orchestrator server 1204 with a job to be accelerated. Subsequently, the micro-orchestrator logic unit 1220 may analyze the code (e.g., microcode) of the requested job to identify one or more functions (e.g., tasks) in the code that may be parallelized. Based on the analysis of the requested job, the micro-orchestrator logic unit 1220 may divide the functions of the job into multiple tasks that may be executed in parallel on one or more accelerator devices 1222 on the accelerator sled 1202. Additionally or alternatively, in some embodiments, the micro-orchestrator logic unit 1220 may transmit the analysis of the requested job to the orchestrator server 1204 such that the orchestrator server 1204 may determine how to divide the job into multiple tasks to be executed on one or more accelerator devices 1222 on multiple accelerator sleds 1202. In such embodiments, each micro-orchestrator logic unit 1220 of one or more accelerator sleds 1202 may receive assigned tasks from the orchestrator server 1204 to schedule the assigned tasks to available accelerator device(s) 1222 based on the job analysis and the configuration of the respective accelerator sled 1202.

In some embodiments, the orchestrator server 1204 may determine that only a portion of the job received from the compute sled 1206 can be accelerated based on the job analysis and the configuration of the respective accelerator sled 1202. In such embodiments, the orchestrator server 1204 may inform the requesting compute sled 1206 that the requested job cannot be accelerated as a whole and/or only a portion of the job can be accelerated. The orchestrator server 1204 may subsequently receive instructions from the compute sled 1206 indicative of how to execute the job. For example, the compute sled 1206 may return a simplified job that can be accelerated as a whole or request to perform the portion of the job that can be accelerated on one or more accelerator sleds 1202.

As discussed above, an accelerator sled 1202 may not include an inter-accelerator communication interface (e.g., a HSSI) between the accelerator devices 1222 (e.g., the accelerator sled 1202 b). In such embodiments, an accelerator device 1222 on an accelerator sled 1202 may communicate with another accelerator device 1222 on the same accelerator sled 1202 via the shared virtual memory 1282 of the memory sled 1208 to execute parallel tasks that share data. Additionally or alternatively, one or more accelerator devices 1222 on an accelerator sled 1202 may communicate with one or more accelerator devices 1222 on a different accelerator sled 1202 via the shared virtual memory 1282 to execute parallel tasks that share data. As such, it should be appreciated that determining whether the tasks of the requested job may be executed in parallel on multiple kernels 1224 is based at least in part on the configuration of each accelerator device 1222.

The main memory 1314 may be embodied as any type of volatile (e.g., dynamic random access memory (DRAM), etc.) or non-volatile memory or data storage capable of performing the functions described herein. Volatile memory may be a storage medium that requires power to maintain the state of data stored by the medium. Non-limiting examples of volatile memory may include various types of random access memory (RAM), such as dynamic random access memory (DRAM) or static random access memory (SRAM). One particular type of DRAM that may be used in a memory module is synchronous dynamic random access memory (SDRAM). In particular embodiments, DRAM of a memory component may comply with a standard promulgated by JEDEC, such as JESD79F for DDR SDRAM, JESD79-2F for DDR2 SDRAM, JESD79-3F for DDR3 SDRAM, JESD79-4A for DDR4 SDRAM, JESD209 for Low Power DDR (LPDDR), JESD209-2 for LPDDR2, JESD209-3 for LPDDR3, and JESD209-4 for LPDDR4 (these standards are available at www.jedec.org). Such standards (and similar standards) may be referred to as DDR-based standards and communication interfaces of the storage devices that implement such standards may be referred to as DDR-based interfaces.

In one embodiment, the memory device is a block addressable memory device, such as those based on NAND or NOR technologies. A memory device may also include future generation nonvolatile devices, such as a three dimensional crosspoint memory device (e.g., Intel 3D XPoint™ memory), or other byte addressable write-in-place nonvolatile memory devices. In one embodiment, the memory device may be or may include memory devices that use chalcogenide glass, multi-threshold level NAND flash memory, NOR flash memory, single or multi-level Phase Change Memory (PCM), a resistive memory, nanowire memory, ferroelectric transistor random access memory (FeTRAM), anti-ferroelectric memory, magnetoresistive random access memory (MRAM) memory that incorporates memristor technology, resistive memory including the metal oxide base, the oxygen vacancy base and the conductive bridge Random Access Memory (CB-RAM), or spin transfer torque (STT)-MRAM, a spintronic magnetic junction memory based device, a magnetic tunneling junction (MTJ) based device, a DW (Domain Wall) and SOT (Spin Orbit Transfer) based device, a thyristor based memory device, or a combination of any of the above, or other memory. The memory device may refer to the die itself and/or to a packaged memory product.

In some embodiments, 3D crosspoint memory (e.g., Intel 3D XPoint™ memory) may comprise a transistor-less stackable cross point architecture in which memory cells sit at the intersection of word lines and bit lines and are individually addressable and in which bit storage is based on a change in bulk resistance. In some embodiments, all or a portion of the main memory 1314 may be integrated into the CPU 1312. In operation, the memory 1314 may store various data and software used during operation of the accelerator sled 1202 such as operating systems, applications, programs, libraries, and drivers.

The compute engine 1310 is communicatively coupled to other components of the accelerator sled 1202 via the I/O subsystem 1320, which may be embodied as circuitry and/or components to facilitate input/output operations with the CPU 1312, the micro-orchestrator logic unit 1220, the memory 1314, and other components of the accelerator sled 1202. For example, the I/O subsystem 1320 may be embodied as, or otherwise include, memory controller hubs, input/output control hubs, integrated sensor hubs, firmware devices, communication links (e.g., point-to-point links, bus links, wires, cables, light guides, printed circuit board traces, etc.), and/or other components and subsystems to facilitate the input/output operations. In some embodiments, the I/O subsystem 1320 may form a portion of a system-on-a-chip (SoC) and be incorporated, along with one or more of the CPU 1312, the micro-orchestrator logic unit 1220, the memory 1314, and other components of the accelerator sled 1202, on a single integrated circuit chip.

The communication circuitry 1330 may be embodied as any communication circuit, device, or collection thereof, capable of enabling communications between the accelerator sled 1202 and another compute device (e.g., the orchestrator server 1204, a compute sled 1206, a memory sled 1208, and/or the client device 1210 over the network 1212). The communication circuitry 1330 may be configured to use any one or more communication technology (e.g., wired or wireless communications) and associated protocols (e.g., Ethernet, Bluetooth®, Wi-Fi®, WiMAX, etc.) to effect such communication.

The illustrative communication circuitry 1330 may include a network interface controller (NIC) 1332, which may also be referred to as a host fabric interface (HFI). The NIC 1332 may be embodied as one or more add-in-boards, daughtercards, network interface cards, controller chips, chipsets, or other devices that may be used by the accelerator sled 1202 to connect with another compute device (e.g., the orchestrator server 1204, a compute sled 1206, a memory sled 1208, and/or the client device 1210). In some embodiments, the NIC 1332 may be embodied as part of a system-on-a-chip (SoC) that includes one or more processors, or included on a multichip package that also contains one or more processors. In some embodiments, the NIC 1332 may include a local processor (not shown) and/or a local memory (not shown) that are both local to the NIC 1332. In such embodiments, the local processor of the NIC 1332 may be capable of performing one or more of the functions of the CPU 1312 described herein. Additionally or alternatively, in such embodiments, the local memory of the NIC 1332 may be integrated into one or more components of the accelerator sled 1202 at the board level, socket level, chip level, and/or other levels. Additionally or alternatively, the accelerator sled 1202 may include one or more peripheral devices. Such peripheral devices may include any type of peripheral device commonly found in a compute device such as a display, speakers, a mouse, a keyboard, and/or other input/output devices, interface devices, and/or other peripheral devices.

The accelerator subsystem 1340 may be embodied as any type of devices configured for reducing an amount of time required to process a requested job received directly or indirectly from a compute sled 1206 executing a workload (e.g., an application). To do so, in the illustrative embodiment, the accelerator subsystem 1340 includes the accelerator devices 1222, each of which may be embodied as any type of device configured for executing scheduled tasks of the requested job to be accelerated. Each accelerator device 1222 may be embodied as a single device such as an integrated circuit, an embedded system, a FPGA, a SOC, an ASIC, reconfigurable hardware or hardware circuitry, or other specialized hardware to facilitate performance of the functions described herein. In some embodiments, the accelerator subsystem 1340 may include a high-speed serial interface (HSSI). As discussed above, the HSSI 1340, in the illustrative embodiment, is an inter-accelerator communication interface (e.g., the inter-accelerator communication interface 1226) that facilitates communication between accelerator devices 1222 on the same accelerator sled 1202 (e.g., the accelerator sled 1202 a).

Referring now to FIG. 14, in the illustrative embodiment, the accelerator sled 1202 may establish an environment 1400 during operation. The illustrative environment 1400 includes a network communicator 1402, an accelerator determiner 1404, a job analyzer 1406, a task scheduler 1408, and a task communicator 1410. Each of the components of the environment 1400 may be embodied as hardware, firmware, software, or a combination thereof. As such, in some embodiments, one or more of the components of the environment 1400 may be embodied as circuitry or a collection of electrical devices (e.g., network communicator circuitry 1402, accelerator determiner circuitry 1404, job analyzer circuitry 1406, task scheduler circuitry 1408, task communicator circuitry 1410, etc.). It should be appreciated that, in such embodiments, one or more of the network communicator circuitry 1402, the accelerator determiner circuitry 1404, the job analyzer circuitry 1406, the task scheduler circuitry 1408, or the task communicator circuitry 1410 may form a portion of one or more of the CPU 1312, the micro-orchestrator logic unit 1220, the memory 1314, the I/O subsystem 1320, and/or other components of the accelerator sled 1202.

In the illustrative environment 1400, the network communicator 1402, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof as discussed above, is configured to facilitate inbound and outbound network communications (e.g., network traffic, network packets, network flows, etc.) to and from the accelerator sled 1202, respectively. To do so, the network communicator 1402 is configured to receive and process data from one system or computing device (e.g., the orchestrator server 1204, a compute sled 1206, a memory sled 1208, etc.) and to prepare and send data to a system or computing device (e.g., the orchestrator server 1204, a compute sled 1230, a memory sled 1208, etc.). Accordingly, in some embodiments, at least a portion of the functionality of the network communicator 1402 may be performed by the communication circuitry 1308, and, in the illustrative embodiment, by the NIC (e.g., an HFI) 1332.

The accelerator determiner 1404, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof as discussed above, is configured to determine a configuration of each accelerator device 1222 on the respective accelerator sled 1202. To do so, the accelerator determiner 1404 is configured to determine the features of hardware components of each accelerator device 1222. For example, the accelerator determiner 1404 determines a configuration of each accelerator device 1222, including a number of kernels 1224 of each accelerator device 1222, whether the respective accelerator device 1222 is communicatively coupled to an inter-accelerator communication interface, such as a HSSI 1226, and/or whether the respective accelerator device 1222 is capable of utilizing the shared virtual memory 1282 (e.g., is capable of mapping memory addresses of the shared virtual memory 1282 as local memory addresses). The accelerator determiner 1404 is further configured to generate accelerator configuration data for each accelerator device 1222 (e.g., any data indicative of the features of each accelerator device 1222), and the accelerator configuration data is stored in an accelerator configuration database 1412. As discussed in detail below, the accelerator configuration data is used to determine how to divide the requested job to be accelerated into multiple tasks that may be executed in parallel on one or more accelerator devices 1222.

The job analyzer 1406, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof as discussed above, is configured to analyze a requested job to be accelerated. Specifically, the job analyzer 1406 is configured to analyze the code of the requested job to determine how to divide functions in the code of the requested job into multiple tasks that may be executed on one or more accelerator devices 1222. Specifically, the job analyzer 1406 analyzes the requested job to determine whether the tasks may be concurrently executed on one or more accelerator devices 1222. It should be appreciated that the job analyzer 1406 may determine that the requested job includes tasks that are capable of being executed in parallel (e.g., either by sharing a data set or because they do not use the output of the other concurrently executed tasks as input) and tasks that are to be executed in sequence (e.g., because they use the final output of another task as an input data set).

For example, the job analyzer 1406 may determine that two tasks (e.g., task A and task B) may share the data associated with a requested job (i.e., read from or write to the different parts of the same data set at the same time, such as encoding or decoding different sections of an image or other data set). In such case, the job analyzer 1406 determines that the two tasks should be executed in parallel in order to reduce an amount of time required to complete the requested job. The job analyzer 1406 may also determine that multiple tasks do not share a data set and the output of one of the tasks does not depend on the output of the other task or vice versa. As such, the job analyzer 1406 may determine that these tasks may also be executed in parallel because they are independent of each other in terms of the data sets that they operate on. On the other hand, if the job analyzer 1406 determines that the output of the one task (e.g., task B) depends on the output of the first task (e.g., uses the final output of task A as an input), the job analyzer 1406 determines that the order of operations of those tasks is important to achieve a correct output; therefore, the task A should be executed prior to the execution of task B. As discussed below, the job analysis is used to schedule the tasks across one or more accelerator devices 1222 for efficient execution of the requested job.

The task scheduler 1408, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof as discussed above, is configured to schedule the tasks of the requested job across one or more accelerator devices 1222. The task scheduler 1408 is configured to maximize the parallelization of the tasks to minimize the execution time of the tasks based on the job analysis performed by the job analyzer 1406. In some cases, if the tasks of the requested job share a data set, the task scheduler 1408 is configured to schedule those tasks to be executed in parallel on one or more accelerator devices 1222 in order to reduce an amount of time required to process the requested job. For example, if a requested job includes compression of an image stored in a shared virtual memory 1282, the task scheduler 1408 divides the job into multiple tasks and schedules the tasks across one or more accelerator devices 1222 in parallel. The one or more accelerator devices 1222 then concurrently execute the compression tasks on different parts of the same image data stored in the shared virtual memory 1282. It should be appreciated that outputs of each task executed on the accelerator device 1222 are combined to obtain a correct output of the job. In some embodiments, the task scheduler 1408 may further identify the communication mechanism (e.g., an inter-accelerator communication interface 1226, shared virtual memory 1282, etc.) based on the accelerator configuration data 1412 for the present accelerator sled 1202. It should be appreciated that if the parallel tasks that share the data are scheduled on the accelerator devices 1222 on the same accelerator sled 1202, the accelerator devices 1222 may establish communication between the accelerator devices 1222 via the HSSI 1226, if the accelerator sled 1202 includes the HSSI 1226, or via the shared virtual memory 1282 to share data and produce a correct output.

If, however, the tasks are independent of one another and do not share data, the task scheduler 1408 may schedule those independent tasks on one or more accelerator devices 1222 on one or more accelerator sleds 1202 to be executed in parallel or at different times. Alternatively or additionally, some of the tasks of the requested job may not be executed in parallel if one or more tasks depend on one or more outputs of one or more previous tasks. In that case, the task scheduler 1408 schedules the dependent tasks to be sequentially executed in a correct order to achieve a correct output. For example, if the received job includes encrypted and compressed data, an output of a decompression task depends on the output of the decompression task (i.e., decompressed encrypted data); therefore, the decryption task should be executed prior to the execution of the decompression task to obtain the correct output. In such case, the task scheduler 1408 schedules the tasks on one or more accelerator devices 1222 such that the decryption task is first executed, followed by the execution of the decompression task. As such, the task scheduler 1408 is configured to examine the characteristics of the tasks determined by the job analyzer 1406, to efficiently schedule the tasks on one or more accelerator devices 1222. By analyzing the data dependencies of the tasks identified by the job analyzer 1406, the task scheduler 1408 is configured to schedule the tasks to maximize the parallelization of the tasks and to minimize the execution time of the job.

The task communicator 1410, which may be embodied as hardware, firmware, software, virtualized hardware, emulated architecture, and/or a combination thereof as discussed above, is configured to facilitate inbound and outbound communications to and from accelerator devices 1222 of the accelerator sled 1202 and/or with accelerator devices 1222 of other accelerator sleds 1202 in the system 1200. Between the accelerator devices 1222 on the same accelerator sled 1202, at least a portion of the functionality of the task communicator 1410 may be performed by the accelerator subsystem 1340, and, in the illustrative embodiment, by the HSSI 1342. Similarly, the task communicator 1410 may access data in the shared virtual memory 1282 to enable a task executed on the present accelerator sled 1202 to access a data set that is also being accessed by a concurrently executing task that utilizes the data set in the shared memory 1282 (e.g., on the same accelerator sled 1202 or on a different accelerator sled 1202). Similarly, the task communicator 1410 may receive output from one task as input for another task and/or provide the output of a task for use as input for by another task.

Referring now to FIGS. 15-17, in use, the accelerator sled 1202 may execute a method 1500 for dividing a requested job to be accelerated into multiple tasks to be executed on one or more accelerator devices 1222. The method 1500 begins with block 1502 in which the accelerator sled 1202 determines a configuration of each accelerator device 1222 of the respective accelerator sled 1202. To do so, in block 1504, the accelerator sled 1202 may determine a connectivity of hardware components of each accelerator device 1222. For example, the accelerator sled 1202 determines a number of kernels 1224 and connectivity between the kernels 1224 of each accelerator device 1222. In some embodiments, in block 1506, the accelerator sled 1202 may determine whether at least one of the accelerator devices 1222 of the accelerator device 1222 is communicatively coupled to the other accelerator device(s) 1222 of the accelerator sled 1202 via an inter-accelerator communication interface, such as an HSSI 1226. Additionally, the accelerator sled 1202 may generate accelerator configuration data for each accelerator device 1222 and may store in the accelerator configuration database 1412, as indicated in block 1508. In block 1510, the accelerator sled 1202 may further determine whether the accelerator sled 1202 is communicatively coupled to the shared virtual memory 1282.

In block 1512, the accelerator sled 1202 determines whether an accelerated job request has been received. The accelerated job request includes a job to be accelerated. In some embodiments, the accelerated job request may be directly received from the compute sled 1206 executing an application. In other embodiments, the accelerator sled 1202 may receive an accelerated job request indirectly from the compute sled 1206 via the orchestrator server 1204. If the accelerator sled 1202 determines that an accelerated job request has not been received, the method 1500 loops back to block 1502 to continue determining the configuration of available accelerator devices 1222 and monitoring for an accelerated job request. If, however, the accelerator sled 1202 determines that an accelerated job request has been received, the method 1500 advances to block 1514.

In block 1514, the accelerator sled 1202 performs a job analysis on the requested job to be accelerated to determine how to divide the job into parallel tasks based on the configuration of the available accelerator devices 1222. To do so, in block 1516, the accelerator sled 1202 analyzes a code of the job and identifies functions in the code that can be parallelized in block 1518. The accelerator sled 1202 may determine whether an order and/or a timing of executions of certain tasks are material to obtain a correct output of the job. For example, the accelerator sled 1202 determines that the tasks may be executed in parallel if the tasks share the same data or if the tasks do not depend on any outputs of previous tasks as inputs. Additionally, the accelerator sled 1202 also identifies the tasks that cannot be executed in parallel. For example, the accelerator sled 1202 may identify the tasks that rely on outputs of previous tasks to be sequentially executed in a correct order to achieve a correct output.

In block 1520, the accelerator sled 1202 determines whether an orchestrator server authorization is required. In other words, the accelerator sled 1202 determines whether an authorization from the orchestrator server 1204 is required to schedule the tasks to one or more accelerator devices 1222 on the accelerator sled 1202. This is because, in some embodiments, the orchestrator server 1204 may determine, based on the job analysis received from one or more accelerator sleds 1202, how the requested job should be divided into multiple tasks that are executed on different accelerator devices 1222 on multiple accelerator sleds 1202 as described in detail below. In some embodiments, the accelerator sled 1202 may query the orchestrator server 1204 whether an authorization is required. Alternatively, in other embodiments, the accelerator sled 1202 may determine whether an orchestrator server authorization is required based on the configuration of the accelerator sled 1202 and/or the job analysis of the requested job.

If the accelerator sled 1202 determines that the orchestrator server authorization is not required, the method 1500 advances to block 1522 shown in FIG. 16. In block 1522, the accelerator sled 1202 determines one or more accelerator devices 1222 that are available on the accelerator sled 1202 to execute one or more tasks. To do so, in some embodiments, the accelerator sled 1202 determines available kernels 1224 of each accelerator device 1222 in block 1524.

Subsequently, in block 1526, the accelerator sled 1202 schedules the tasks to one or more available accelerator devices 1222 based on the job analysis. As described above, the accelerator sled 1202 has analyzed the requested job to be accelerated to identify the tasks that can be executed in parallel to operate on the same data set, the tasks that may or may not be executed in parallel (e.g., use independent data sets), and the tasks that are to be executed in sequence because of their dependency on the final output of other tasks. Based on the job analysis, the accelerator sled 1202 is configured to schedule the tasks on one or more accelerator devices 1222 to maximize the parallelization of the tasks to reduce a total execution time of the job. To do so, in some embodiments, the accelerator sled 1202 may enable a parallel execution of tasks in block 1528. In such embodiments, the parallel execution of tasks on one or more accelerator devices 1222 on the accelerator sled 1202 is achieved by the inter-accelerator communication interface 1226 between the one or more accelerator devices 1222 on the accelerator sled 1202. However, it should be appreciated that the parallel execution of tasks may be achieved by virtualization of the shared data using the shared virtual memory 1282. Additionally, in some embodiments in block 1530, the accelerator sled 1202 may confirm the availability of one or more accelerator devices 1222 to execute one or more tasks (e.g., that the accelerator device 1222 is not presently experiencing a load above a predefined threshold amount, that one or more kernels of the accelerator device 1222 are not presently executing a task, etc.).

In block 1532, the accelerator sled 1202 may execute multiple scheduled tasks in parallel. For example, in some embodiments in block 1534, if the accelerator devices 1222 of the accelerator sled 1202 are configured to execute tasks that share the same data, one of the accelerator devices 1222 of the accelerator sled 1202 may communicate with the other accelerator device 1222 of the same accelerator sled 1202 using the inter-accelerator communication interface 1226 (e.g., the HSSI) or the shared virtual memory 1282, based on the configuration of the accelerator sled 1202, to share the data. Subsequently, in block 1536, the accelerator sled 1202 combines the outputs of the tasks to obtain an output of the job in block 1538. It should be appreciated that if the tasks are scheduled on the accelerator devices 1222 on the accelerator sled 1202 that has the HSSI 1226 (e.g., the accelerator sled 1202 a), the accelerator devices 1222 may communicate with one another via the HSSI 1226 to combine the outputs of the tasks to obtain the output of the job. If, however, the tasks are scheduled on the accelerator devices 1222 on the same accelerator sled 1202 (e.g., the accelerator sled 1202 b) that does not have a HSSI 1226, the accelerator devices 1222 may communicate with one another via the shared virtual memory 1282 to combine the outputs of the tasks to obtain the output of the job.

Referring back to block 1520 in FIG. 15, if the accelerator sled 1202 determines that the orchestrator server authorization is required, the method 1500 advances to block 1538 shown in FIG. 17, in which the accelerator sled 1202 transmits the job analysis performed by the accelerator sled 1202 to the orchestrator server 1204. In other words, the orchestrator server 1204 receives job analyses from multiple accelerator sleds 1202 and determines how to efficiently divide the requested job into multiple tasks to be executed on multiple accelerator devices 1222 on the multiple accelerator sleds 1202 using a process similar to that described above with reference to blocks 1522, 1526 of FIG. 16.

Subsequently, in block 1540, the accelerator sled 1202 determines whether an authorization from the orchestrator server 1204 has been received. If the authorization is not received during a predefined period of time, the accelerator sled 1202 determines that the accelerator devices 1222 of the accelerator sled 1202 have not been selected to execute the tasks by the orchestrator server 1204, and the method 1500 advances to the end.

If, however, the accelerator sled 1202 determines that the authorization has been received, the method 1500 advances to block 1542. In block 1542, the accelerator sled 1202 receives one or more assigned tasks to be executed on the accelerator sled 1202. If the accelerator sled 1202 determines that the assigned task(s) is not received during a predefined period of time in block 1544, the method 1500 advances to the end. If, however, the accelerator sled 1202 determines that the assigned task(s) has been received, the method 1500 advances to block 1546.

In block 1546, the accelerator sled 1202 determines one or more available accelerator devices 1222 of the respective accelerator sled 1202. Specifically, the accelerator sled 1202 determines available kernels 1224 of each accelerator device 1222 in block 1548 to determine how to schedule the assigned tasks across the multiple kernels 1224 of the accelerator devices 1222 on multiple accelerator sleds 1202.

Subsequently, in block 1550, the accelerator sled 1202 schedules the assigned tasks to the accelerator devices 1222 based on the job analysis to maximize the parallelization of the tasks to reduce a total execution time of the job. As discussed above, the job analysis indicates whether the tasks may be executed in parallel or require to be executed in a particular sequence. To do so, in block 1552, the accelerator sled 1202 may enable parallel execution of independent tasks. In such embodiments, the parallel execution of tasks on multiple accelerator devices 1222 on different accelerator sleds 1202 is achieved by sharing a data set using the shared virtual memory 1282 (e.g., mapping memory addresses of the shared virtual memory 1282 as local memory for each accelerator device 1222). It should be appreciated that the inter-accelerator communication interface 1226 is limited to providing the communication between the accelerator devices 1222 on the same accelerator sled 1202. In some embodiments, in block 1554, the accelerator sled 1202 may confirm that the accelerator devices 1222 on the respective accelerator sled 1202 are available to concurrently execute the multiple tasks at the same time.

Subsequently, in block 1556, the assigned tasks are executed in parallel on multiple accelerator devices 1222, potentially on different accelerator sleds 1202. For example, if the assigned tasks share the same data, the multiple accelerator devices 1222 on different accelerator sleds 1202 may concurrently execute the assigned tasks using the shared virtual memory 1282 to read from and/or write to the shared data present in the shared virtual memory 1282. In some embodiments, some of the assigned tasks may be assigned to the accelerator devices 1222 on a single accelerator sled 1202 that may or may not have an inter-accelerator communication interface 1226 (e.g., HSSI). If the tasks are assigned to the accelerator devices 1222 of the accelerator sled 1202 that has the HSSI 1226, in block 1558, the accelerator devices 1222 on that accelerator sled 1202 may concurrently execute the assigned tasks using the HSSI 1226 to share the data. If, however, the tasks are assigned to an accelerator sled 1202 that does not have a HSSI 1226 (e.g., the accelerator sled 1202 b), the accelerator devices 1222 may concurrently execute the assigned tasks using the shared virtual memory 1282 to read from and/or write to the shared data stored in the shared virtual memory 1282, as indicated in block 1560. Subsequently, in block 1562, the accelerator sled 1202 combines the outputs of the assigned tasks of the corresponding accelerator device 1222 to obtain an output of the job.
